Moreover, the prevalence of valvular heart disease is steadily increasing, especially in industrialized countries, and the problem of lifelong efficient anticoagulation of these patients remains fundamental, especially in the context where vitamin K antagonists continue to be the current standard of anticoagulation despite a level of oscillating anticoagulation. In this setting, avoiding prosthetic valve thrombosis after surgery is the number one objective for both the patient and the responsible physicians. Although rare, this complication is life threatening, with the sudden onset of acute cardiac failure such as acute pulmonary edema, cardiogenic shock, or sudden cardiac death and inadequate anticoagulation remaining the leading cause of prosthesis thrombosis, along with other risk factors. The availability of multimodal imaging techniques enables and encompasses to a full extent the diagnosis of mechanical valve thrombosis. The gold-standard diagnostic methods are transthoracic and transesophageal echocardiography. Moreover, 3D ultrasound has undoubted value in giving a more accurate description of the thrombus\u2019s extension. When transthoracic and transesophageal echocardiography are uncertain, the multidetector computer tomography examination is an important complementary imaging method. Fluoroscopy is also an excellent tool for evaluating the mobility of prosthetic discs. Each method complements the other to differentiate an acute mechanical valve thrombosis from other prosthetic valve pathologies such as pannus formation or infective endocarditis and aids the physician in accurately establishing the treatment method (surgical or pharmaceutical) and its optimal timing. The aim of this pictorial review was to discuss from an imagistic perspective the mechanical prosthetic aortic and mitral valve thrombosis and to provide an overview of the essential role of non-invasive exploration in the treatment of this severe complication.<\/jats:p>","DOI":"10.3390\/jpm13060967","type":"journal-article","created":{"date-parts":[[2023,6,8]],"date-time":"2023-06-08T03:29:48Z","timestamp":1686194988000},"page":"967","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Diagnosis of Left-Sided Mechanical Prosthetic Valve Thrombosis: A Pictorial Review"],"prefix":"10.3390","volume":"13","author":[{"given":"Adela","family":"Serban","sequence":"first","affiliation":[{"name":"Cardiology Department, Heart Institute Niculae St\u0103ncioiu, 19\u201321 Motilor Street, 400001 Cluj-Napoca, Romania"},{"name":"5th Department of Internal Medicine, Faculty of Medicine, Iuliu Ha\u0163ieganu University of Medicine and Pharmacy, 8 Victor Babes Street, 400012 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3964-6995","authenticated-orcid":false,"given":"Alexandra","family":"Dadarlat-Pop","sequence":"additional","affiliation":[{"name":"Cardiology Department, Heart Institute Niculae St\u0103ncioiu, 19\u201321 Motilor Street, 400001 Cluj-Napoca, Romania"},{"name":"5th Department of Internal Medicine, Faculty of Medicine, Iuliu Ha\u0163ieganu University of Medicine and Pharmacy, 8 Victor Babes Street, 400012 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5540-3478","authenticated-orcid":false,"given":"Alexandru","family":"Achim","sequence":"additional","affiliation":[{"name":"Cardiology Department, Heart Institute Niculae St\u0103ncioiu, 19\u201321 Motilor Street, 400001 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dana","family":"Gavan","sequence":"additional","affiliation":[{"name":"Cardiology Department, Heart Institute Niculae St\u0103ncioiu, 19\u201321 Motilor Street, 400001 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diana","family":"Pepine","sequence":"additional","affiliation":[{"name":"Cardiology Department, Heart Institute Niculae St\u0103ncioiu, 19\u201321 Motilor Street, 400001 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raluca","family":"Rancea","sequence":"additional","affiliation":[{"name":"Cardiology Department, Heart Institute Niculae St\u0103ncioiu, 19\u201321 Motilor Street, 400001 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1944-4088","authenticated-orcid":false,"given":"Raluca","family":"Tomoaia","sequence":"additional","affiliation":[{"name":"5th Department of Internal Medicine, Faculty of Medicine, Iuliu Ha\u0163ieganu University of Medicine and Pharmacy, 8 Victor Babes Street, 400012 Cluj-Napoca, Romania"},{"name":"Clinical Rehabilitation Hospital, 46-50 Viilor Street, 400347 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"589","DOI":"10.1093\/ehjci\/jew025","article-title":"Recommendations for the imaging assessment of prosthetic heart valves: A report from the European Association of Cardiovascular Imaging endorsed by the Chinese Society of Echocardiography, the Inter-American Society of Echocardiography, and the Brazilian","volume":"17","author":"Lancellotti","year":"2016","journal-title":"Eur.
